Increasingly, software is the tool with which users interface with their measurement systems. Metrology software can perform a wide range of functions. Processes such as the actual measuring, the data collection, storage and reporting can be done entirely by the program itself, or semi-automatically with greater manual input. A variety of different measurement purposes can be facilitated with the use of the right software, such as: equipment inspection; image analysis; precision mold making; totalized weighing; and too many others to be comprehensively listed here.

Graphical representation of collected data is a major feature of measurement software. The input from lasers, scanners and/ or photogrammetry, to name just three, can be instantly translated into two- or three-dimensional images. Three-dimensional images can be observed from a variety of angles to ascertain that the scanned object meets a user’s standards, or if a part is out of tolerance and needs to be corrected. Also, this kind of software can be used to generate instant gages. When a gage is stored as a template, other measured items can be compared against it to determine if correction is required. The ability for a user to get instant feedback is a major plus, potentially saving hours of wasted effort.

Furthermore, software obviates the need for pre-planning and drawing of gages beforehand, since everything can be done in the program itself. Software can also be used for information storage and reporting. Databases and statistical summaries can be created. For example: in weighing, software can be used with an analytical balance to store results and generate reports on the collected data. The important point to consider in this regard is what kind of reporting you need for your particular field, and whether the software can interface properly with other programs, especially spreadsheet generators like Lotus, Excel and Access.

Another factor that must be considered in the selection and purchase of software is: will this software interface with my data collection devices? The right software can turn a handheld laser scanner and a lab balance into a pill counter. Someone using a portable arm with a laser tracker to inspect large objects will need a program very different from someone analyzing images of circuitry. It is important that the software should interface with a wide variety of measurement device types from different manufacturers. This will save headaches down the line as your other equipment is replaced or upgraded.

Furthermore, the selected software should be as intuitive as possible. Software creators like to tout the user-friendliness of their products, but some are more honest about this than others. It is important to gather as much information about the software as possible, if not actually try it out with your system before purchasing.
